This is how ground effects work in a nutshell

There are two ways to generate downforce. One is with all manner of wings and spoilers on the surface of the vehicle. The other is with ground effects. One you can clearly see, the other remains something of a hidden mystery. Fortunately, the good folks at Lotus and Goodwood are here to dumb it down for us non-engineer types. It's called Bernoulli's Principle, named after Swiss physicist Daniel Bernoulli who literally wrote the book on the subject way back in the 1700s. Countless engineers have spent their careers focused on its study and application, but the crux of the matter is that, as the speed of air (or other "fluid") increases, pressure decreases. Play with the air's increasing speed and decreasing pressure just right and you can generate downforce underneath the body of a car without significantly increasing drag as you would with surface spoilers. For evidence of how Bernoulli's Principle applies in practical terms, just look at the last Ferrari to pack a turbocharged V8 in the middle and the latest one. The F40 had a giant wing on the back, where the 488 GTB has none. But because the 488 uses underbody aerodynamics (or "ground effects"), it generates significantly more downforce than the winged F40 ever could, and at lower speeds. Ferrari, however, was not the first outfit to harness the power of ground effects. Lotus did with the legendary 79 that Mario Andretti drove to the world championship back in 1978. That was the genius of Colin Chapman, and to explain how it all works in layman's terms, our friends over at Goodwood Road & Racing brought in Colin's son Clive Chapman, head of Classic Team Lotus, to put together the video above.

James Bond Lotus submarine sells in London for $966,560

With the $966,560 sale ($863,000 plus a 12-percent buyer's premium) of the white 1977 Lotus Esprit S1 submarine used in the 1977 James Bond film The Spy Who Loved Me, we now know "the Roger Moore discount."
Recall that Sean Connery's silver 1964 Goldfinger Aston Martin DB5 was sold by RM Auctions in London in 2010 for $4.6 million. Three years later, the same auction company in the same city has sold the aforementioned Lotus for just under $1 million.
An unscientific poll of those in the room showed that people preferred Sean Connery's Bond to Roger Moore's by a rate of four to one. And thus it translated into the bidding for their respective cars. No word on the identity of the buyer or his plans for what is, in fact, a working submarine.

Lotus opens the 2013 Formula One season with the launch of the E21 [w/video]

Lotus has broken the seal on the 2013 Formula One season, launching the E21 car at its factory in Enstone. With the regulations this year quite similar to those of last year, there are no dramatic changes in form compared to the E20. After some teams lobbied to be able to cover the stepped nose with a "vanity panel," Lotus retained the configuration, the team's technical director saying that the panel would add more weight and didn't make sense to put on the car unless it also added performance.
Beyond that, the E21 is said to be an comprehensive advance in its details - the suspension gets a new layout, the Coanda exhaust and the passive double DRS system are evolutions from last year, the front wing is "a continuation of concepts" from 2009.
After securing fourth in the Constructor's Championship last year, this is the chassis that drivers Kimi Räikkönen and Romain Grosjean will use to try and move the team up a place, which would mean beating one of the big three teams over the course of the season. The quietly and impressively consistent Räikkönen managed third in the Driver's Championship, and we're sure he wouldn't mind a move up in the standings, either.
